Here is the skimage doc: orientation : float. Angle between the 0th axis (rows) and the major axis of the ellipse that has the same second moments as the region, ranging from -pi/2 to pi/2 counter-clockwise.

This gives a circularity of 1.9865, which is higher than 1 (what I intuitively think of as the max possible circularity). The area of the particle is 5, which is expected, but the perimeter is 5.6240, and I can't seem to figure out how regionprops is getting that value.

skimage.measure.find_contours(array, level, fully_connected='low', positive_orientation='low') Find iso-valued contours in a 2D array for a given level value. Uses the “marching squares” method to compute a the iso-valued contours of the input 2D array for a particular level value.

ball¶ skimage.morphology.ball (radius, dtype=<class 'numpy.uint8'>) [source] ¶ Generates a ball-shaped structuring element. This is the 3D equivalent of a disk. A pixel is within the neighborhood if the euclidean distance between it and the origin is no greater than radius.
